假设访问的views.py如下

1.使用url配置默认页

from django.conf.urls import url
from django.contrib import admin
from django.urls import path

from HelloWorld import views

urlpatterns = [
  path('admin/', admin.site.urls),
  url('^$', views.hello),
]

这样可以访问http://127.0.0.1:8090/

2.使用path配置默认页

from django.contrib import admin
from django.urls import path

from HelloWorld import views

urlpatterns = [
  path('admin/', admin.site.urls),
  # url('^$', views.hello),
  path('', views.hello),
]

这样也可以访问http://127.0.0.1:8090/

3.使用path配置hello页

from django.contrib import admin
from django.urls import path

from HelloWorld import views

urlpatterns = [
  path('admin/', admin.site.urls),
  # url('^$', views.hello),
  # path('', views.hello),
  path('hello/', views.hello),
]

这样可以访问http://127.0.0.1:8090/hello/

4.使用url和正则

from django.conf.urls import url
from django.contrib import admin
from django.urls import path

from HelloWorld import views

urlpatterns = [
  path('admin/', admin.site.urls),
  # url('^$', views.hello),
  # path('', views.hello),
  # path('hello/', views.hello),
  url('^hello', views.hello),
]

可以访问http://127.0.0.1:8090/hello+任意字符

5.如果有多个app，还可以使用include

from django.contrib import admin
from django.urls import path, include

from CRUD import views

urlpatterns = [
  path('admin/', admin.site.urls),
  path('', views.login_html),
  path('login.html/', views.login_html),
  path('index.html/', views.index_html),
  path('debug.html/', views.debug_html),
  path('debug/', views.debug),
  path('login/', views.login),

  path('one/', include('Model.urls')),
  path('two/', include('Model2.urls')),
  path('three/', include('Model3.urls')),
  path('four/', include('Model4.urls')),
]
